摘要： Integrated circuit transmitters allow for ultrasound imaging with both pulsed and continuous waves. High voltage and low voltage switches are integrated onto a same semiconductor chip. The high voltage switches are used for pulsed wave operation, and the low voltage switches are used for continuous wave operation. Power dissipation may be reduced by using low voltage circuits for the continuous wave operation. Both the pulsed and continuous waveforms are output on a common output from the integrated circuit. For continuous wave operation, one or more of the high voltage switches is used to provide a low resistance path to the common output or ground. For pulsed wave operation, one or more of the low voltage switches is used to provide a low resistance path to a common output or ground. A switch used for generating waveforms is also used for forming a low resistance path.

摘要： A plurality of application specific integrated circuit (ASIC) chips with different functions is provided. Each of the ASICs performs one or more functions along an ultrasound data path. The chips include communications protocols or processes for allowing scaling. For example, ASICs for backend processing include data exchange ports for communicating between other ASICs of the same type. As another example, receive beamformer ASICs cascade for beamformation. By providing ASICs implementing many or most of the ultrasound data path functions, with scalability, the same ASICs may be used for different system designs. A family of systems from high end to low-end using the same types of ASICs, but in different configurations, is provided.

摘要： An ultrasound front end circuit (1000) according to the present invention includes a single transformer core which performs all of the pulse and transmit/receive switching functions. A transmit pulser (1102) is formed by a pair of transistor switches in combination with a transformer having first windings (N1, N2) driven by a DC source. A secondary winding (N3) provides a voltage step up for transmitted wave forms and a pair of anti-parallel shunt diodes (1014) on the receiver terminal direct the transmitted 0 waveform to the ultrasound transducer (1024). A floating third winding (N4) shunted by a current biased diode bridge (1002) provides an effective open circuit across the secondary winding while transmitting high amplitude signals. The third winding (N4) and diode bridge (1002) act to short circuit the secondary winding (N3) while receiving small amplitude signals, thus providing a direct connection between the transducer (1024) and receiver (1020).

摘要： Modular electronics are provided for a multi-dimensional array. The electronics are positioned perpendicular to the array in modules. The modules include frames to support the electronics and provide for electrical connection between the array and the electronics. The frames include thermally conductive material to transfer heat away from the electronics and the array. The frames form a surface to support part of the array and a single layer of flexible circuit material with pads and traces over the surface for electrical connection. The flexible circuit material allows connection to the electronics at a pitch different than the pitch of the array. The modules allow the same electronics parts to be used with different sized arrays. The traces and pads of the flexible circuit material may be changed for different arrays without having to redesign the electronics and/or modules.
